0 is most likely the answer. considering you didn’t add a picture or anything like that.
Answer:
An independent system of equations
First, you need to find the average rate of change (the number of bolts produced per minute). To do this you divide 440 by 48, which equals approximately 9.16; therefore, the machine produces approximately 9.16 bolts per minute. To find out how many bolts would be produced in 30 minutes, multiply 9.16 by 30, which is 274.8. Round this number and you get 275 as your final answer. I hope I helped :)
Answer:
h(n+1) = h(n) - 7
Step-by-step explanation:
Our objective is to write the expression for h(n+1) in terms of h(n) which equals -31 -7(n-1)
So we use the given formula to find what h(n+1) is:
h(n+1) = -31 -7((n+1)-1)
h(n+1) = -31 -7(n+1-1)
we now re-arrange the order of terms inside the parenthesis without combining like terms:
h(n+1) = -31 -7(n-1+1)
and use distributive property to multiply "-7" times the "+1" term and get it extracted from inside the parenthesis:
h(n+1) = -31 -7(n-1) -7
Notice that this way we were able to preserve the form of the term h(n) "-31 -7(n-1)" , and see what is the modification introduced to it when finding the term h(n+1). We now replace "-31 -7(n-1)" by "h(n)" in the above equation:
h(n+1) = -31 -7(n-1) -7
h(n+1) = h(n) - 7
And this is the recursive formula that tells us how to construct the following term of a sequence by knowing the previous one.
I believe it's -5.25 because it's adding .50 everytime
